Is there some reason you chose the SOK rather than say, Battleborn?

OP here. Thanks for all your help. Here is where I am at with this, and I'd appreciate your thoughts: Plan is to install 2, 100 ah lithium batteries, a 2000w inverter and a DC-DC charger. (again, just trying to power 1350w microwave as my largest load. I'm looking at 2 possible approaches. 1.I simply buy batteries, inverter, dc-dc from Renogy so everything is the same manufacturer. Avoid any interconnection, compatibility issues. 2. I prefer some specific components, so the other option is: Buy 2, 100 ah SOK batteries. A Victron Orion 30 a DC-DC charger (Im told they are superior). Then the Renogy 2000w inverter that you guys have been talking about and recommending here. I am not looking for the cheapest, I am looking for the safest, most reliable approach. What say you? Option 1 or 2, or a different one? Thank you!562Views0likes0CommentsRe: Inverter and battery sizing to power my camper microwave

Even if it only has a 4000 watt *peak* surge/power rating (vs. 4000 watt for 5 sec), it still may work. For me, it would be worth the risk of a simple return to potentially save $400-$800. That's a good suggestion - and low risk. But I just looked at this Xantrex: https://www.donrowe.com/Xantrex-806-1220-PROwatt-SW-2000-p/806-1220.htm More expensive, for sure but the specs say: 1800 watts continuous power output 2000 watts for 5 minutes 3000 watts surge (peak power) Pure sine wave output (< 5% THD ) 5 minutes @ 2000 watts? Am I reading that right - that's differerent from peak power, I assume? I'm thinking that would easily run my MW561Views0likes0CommentsRe: Inverter and battery sizing to power my camper microwave

I have no reason to doubt you were quoted 4000 watts for 5 sec. I've had all kinds of specs and claims quoted to me over the years. Interesting that Renogy fails to advertise this outstanding capability anywhere in writing. All their online literature and specs simply claim a generic 4000 watt *peak* surge/power rating. For the sake of discussion, I will say this: *IF* this $300 (US) 2000 watt Renogy RNG-INVT-2000-12V-P2-US inverter is capable of 4000w for 5 sec, it would make it one of the best performing high-frequency 2000w inverters on the market, regardless of price. Unfortunately, this is a huge if. As they say, if it sounds too good to be true, it probably is. Really? I'm trying to verify this. How did you get the info? I am just about to pull the trigger on an inverter and want to make sure it will power my 900 w microwave that shows a draw of 1350 watts, as stated earlier. I have been wavering between Renogy, GoPower and Victron. Victron is a lot more expensive, but I want to do this right. GoPower is about $700 US and Renogy a lot cheaper. I don't want to cheap out, but don't want to spend the extra if the Renogy 2000 w in the $300 range will really work well. How do I confirm this? Thanks!561Views0likes0CommentsRe: Inverter and battery sizing to power my camper microwave

I do agree the lack of companies putting this in there advertising makes things a little more difficult. personaly I have never been met with any issues when I email the company and ask for that information. You mentioned the Renogy 2000w PSW inverter. Very popular unit. Always wondered what time/duration they used for their peak rating. Did you happen to get this info? No, I have not been able find that information - and would like to.346Views0likes0CommentsRe: 8 Gauge Wire
Good info, all. The specs call for 4 to 6 awg depending on distance. My distance falls in the middle of the range listed for the run. I would like to run 4 awg from truck batt to truck bed, then step down to 6 for the last 6 or 7 feet of the run. Any concerns with that?932Views0likes0CommentsRe: Inverter and battery sizing to power my camper microwave

Did you wire it to the main camper power center and shore power connection?297Views0likes0CommentsRe: Inverter and battery sizing to power my camper microwave
Continuing - I see that I MIGHT have just enough room to use a Renogy 3000 w instead of 2000. The larger Giandel will not fit. If I upsize, I assume that my microwave would not be an issue, but does that increase draw on my batteries enough to be a concern? Sorry, I'm still learning and appreciate all of your help very much297Views0likes0CommentsRe: Inverter and battery sizing to power my camper microwave
This is great info, thanks. I am trying to figure out what the inverters I am looking at have for surge and inrush capacity. I have specs for the Renogy 2000w that lists "peak surge" as 4000 w, no mention of inrush. The Giandel 2200w lists neither. I have screenshots of the specs but dont see where I can attach them here. So, how do I find this information? Write the manufacturer? And if I do find it, what are the thresholds that are acceptable for my application/plan?297Views0likes0Comments
